Two screens at the same time. That is the central feature of Lenovo’s Yoga Book 9i. This dual-screen clamshell touchscreen laptop replaces the traditional keyboard deck with a second touchscreen on the bottom half. Lenovo has been experimenting with unconventional laptop designs for years, but the Yoga Book 9i is its best execution of the dual-screen form factor. It offers certain advantages over other laptops, particularly for those accustomed to working at a desk. Lenovo has implemented clever software and hardware tricks to make this device work, resulting in a surprisingly usable device with two screens and no built-in keyboard. However, it is not likely to replace traditional clamshell laptops just yet.
The Yoga Book 9i looks similar to other Yoga models and 2-in-1 convertible laptops at first glance. It is about the same thickness as a MacBook Pro when closed, with rounded, polished sides, and a dark blue aluminum chassis. The top half has an extra lip for easy opening and a Windows Hello-compatible webcam. However, the bottom half of the laptop is thicker and houses the computing components. There are three Thunderbolt 4 USB-C ports, but the absence of a 3.5mm headphone jack may disappoint some users.
When you open the Yoga Book 9i, you’ll notice the two 13.3-inch OLED touchscreens with 16:10 aspect ratios. They have vibrant colors, high peak brightness, and good color matching. The device supports various postures, but using it in clamshell mode with the virtual keyboard is not ideal. Typing on the virtual keyboard is a subpar experience, although using the included Bluetooth keyboard is much better. The touchscreen also includes a virtual trackpad, but it feels sticky and is not as smooth as a physical trackpad.
The most productive posture involves using the Bluetooth keyboard and folding stand provided with the device. Propping the 9i almost vertically with the stand allows you to use both screens simultaneously, making it a multi-monitor productivity machine. Windows recognizes the two screens as separate displays, enabling various practical use cases. The stand also serves as a travel case for the keyboard. Overall, this is the Yoga Book 9i’s best and most useful form.
While the device comes with a stylus that can be stored in the folding stand, utilizing the two screens requires additional setup compared to traditional laptops. It also doesn’t work well on the lap. However, if you already carry a portable USB-C monitor or use your laptop at a fixed desk, this won’t be a major issue. The stylus can be useful for taking handwritten notes or using the space above the keyboard as a scratch pad.
In conclusion, the Lenovo Yoga Book 9i offers the advantage of having two screens simultaneously, but it has some compromises and requires setup. It is a notable execution of the dual-screen form factor, but it may not fully replace traditional laptops for most users.
